This physics student has an ingenious hack to the “only bring in one side of a bit of paper for formulas” rule

This is Rob Schaller and he’s been called out by his old physics professor Robert McNees for this outrageous hack.

Flashback to last Spring, when I told my E&M students they could use one side of a piece of paper as a final exam formula sheet. pic.twitter.com/S0QyLaOXyZ

If you don’t quite follow then this is a Möbius strip. Make one at home by taking a roll of paper and making a twist before you connect it to the start of the loop. Then there’s only ever one side that goes on forever.

Genius.
